Break in period

Dopogue, Great observation and I think you're right on. On the Raysonic I had expectations based on the review in 6moons and that is what I focused on for the first couple of hours out of the box. Warm, less resolution, rolled highs. Yep. Then the next day I started listening to it critically and concluded that the reviewer was FOS and, at a minimum, the tubes were a terrible match, no 'breaking in' could fix this sound! Dull, bloated, poor resolution, etc.

I was wrong! I rolled a ton of tubes in the Raysonic and my other stuff trying to get what I expected in the first place. Many weeks later I went back to the same tubes in the Raysonic and its IMHO great, especially at the price! Ditto my Tylers, dammed near sent them back to Tyler!

And for flatearther's amoungst us, my listening was always with other broken in speakers and CDP's available for comparison so I was able to track the changes. You're intitled to your opinions and experiences, but they are not universal for a good reason.

Shadrone,

A quick question. Do you assume that manufacturers only use new component parts when they make their prototypes and that their designs are only to be heard with new parts. I think it is reasonable to assume they do not, and that your product's critical parts age to approximate those of the manufacturers prototype.

Or are you saying that parts aging never changes the components contribution to the sound?

BTW, how do you define 'significant'.

Lastly how did you determine the appropriate length of time for the breakin to occur. It seems to me that listening skills/experience/interest are more determinative of the length of the break in period than anything else.

For other naysayers......

Everything is new, degrades and dies. Changes occur. Those are immutable 'facts'.

Why do I seem to note that when believers post they always post regarding the equipment that they observed the break in occur. Conversely, the nay sayers NEVER give any specificity to support thier positions. I would like them to tell us:
1) What credentials do you hold
2) What experience do you have
3) What have you actually listened to
4) Under what circumstances did you listen to the equipment that caused you to form your opinion.

Tell us poor believers what causes you all to want to deprive us of out poor beliefs. Absent 'facts' to support your beliefs that is!

Let us hear from you, but no more one liners please.
